This installation documentation is for the HO Scale Broadway Limited RSD-15 (High Hood) using a TCS WOW121-Diesel Decoder, IB-MB2 Motherboard with built in Keep Alive® and 28mm WOWSpeaker. This installation also uses a 6-Pin JST harness for "IB" motherboards to wire in the headlights. This installation was performed by DCC Xpress Installations.
The speaker in this installation may be substituted for a "High Bass" 28mm WOWSpeaker for better bass response and volume! Check out the video linked at the bottom of this page for an example of the installation process and demonstration of the sound quality using that speaker.
NOTE: This installation process applies to both the High-hood and Low-hood variants of the RSD-15 from Broadway Limited; however, it is important to know that there are several generations of this model which used different sound decoders. The model depicted in this installation documentation had a DC board installed with JST connectors compatible with our IB-MB2 motherboard. Most QSI-generation decoders use the same style of plugs. If you have a model equipped with a Paragon decoder, the connectors may not be compatible. You can still use the IB-MB2 motherboard by wiring in our compatible wiring harnesses.

Please do not use any flux either liquid or paste on the mother board. Over time, the acidic properties of liquid or paste flux will begin eating away at the fiberglass PCB and will damage it. Use only Rosin-core solder or no-clean flux approved for electronics use.
TCS recommends the use of Kester "44" Sn63 Pb37, .015" diameter Rosin-core solder. Kester part number 24-6337-0007.
You can order this solder from the following retailers:
Digikey - PN:KE1110-ND
Techni-Tool - PN:488SO6775
When stripping wire, only strip a tiny little bit of the insulation. Strip no more than a 1/32 of an inch. When the wire gets tinned with solder, the insulation will shrink back more. Try to not expose any more wire than half the length of the solder pad at most. In no case should solder or exposed wire wire ever be outside the boundary of the the solder pad you are attaching a wire to.
